The Rock's Mom -- Car Smashed by Drunk Driver in Head on Collision

Exclusive Details
The Rock says his mom, Ata Maivia-Johnson and his cousin were struck HEAD ON by a drunk driver this week ... and luckily, they survived.

Dwayne Johnson's uncle Afa tells us Ata and Lina Fanene were driving home from a fundraiser their family runs every year -- the Usos Foundation Banquet -- when they were crashed into by the alleged drunk driver.

Both women were rushed to a local hospital and we're told Ata was hospitalized for 3 nights. Afa wouldn't say what injuries the 65-year-old sustained ... but he did tell us it was a very scary scene.

The Rock posted a picture of the crash and his mom's white Escalade -- the one he bought her for Christmas in 2012 -- clearly totaled. Same goes for the other car involved.

Fanene -- who currently works for WWE's NXT division -- posted a photo of the actor/wrestler visiting her in the hospital.

Ata and Lina also posed for a pic in the SUV on August 2nd on their way to the fundraiser.

The Rock tweeted, "First reaction is to find the person who did this and do unrelenting harm to them. But then you realize the most important thing is my family lived thru this and we can hug each other that much tighter these days."
